The display operation unit selects the touch type color LCD display, the whole Chinese menu, the interface is clear and direct, the operation is simple square. The test does not need any auxiliary equipment, automatic control, fool operation, quick, simple and convenient.

3) there are two ways to test the instrument: automatic test and manual test. It has an automatic steady flow system.

4) only set a good target current, without manual monitoring, only set the test, current and step length, save manual pressure, manual recording, depict the curve and other tedious labor, reduce labor intensity, improve work efficiency can also be read on the computer after the work can be read on the computer.

5) automatic alarm function with over limit value has reliable self protection function of overheat, overcurrent, overvoltage and short circuit. The protection of AC voltage regulator should adopt microcomputer automatic protection control and mechanical fretting limit switch double protection to ensure the normal work of constant current power supply and improve the safety and reliability of the product.

6) humanized interface, the software interface is friendly;

7) automatically adjust the source of alternating current.

8) custom test modules can be customized according to user requirements, software free upgrade for life.

9) adopt 64 way temperature measuring module (optional up to 200 test temperature points).

10) increasing power compensation system

11) data export function. Through U disk, the device data can be stored on the computer for further processing and printing.

New features

1, the switch and voltage regulator input from the power supply to the voltage regulator output to the input switch of the upcurrent, that is, the front stage and the rear grade; corresponding to the post grade, the front grade; the emergency stop; the mutual locking (the front stage is incompatible, the post level not up; the post level is not divided, the former level can not be divided!).

2. It has zero position locking function of voltage regulator.

3. The upflow body is centered on open holes and high current output, and can be directly worn through various conductors to facilitate any experiment and raw flow test.

4. The special structure can effectively control the vortex heating problem of the upflow body bracket and shell metal.

5. High strength wheels are installed at the bottom of the lifting device to facilitate movement.

6, the wireless control part, including the front stage, the post grade, the upflow, the downflow, the post grade, the emergency stop button, and the locking requirements of the control cabinet (the front level is not fit, the post level is not up, the post level is not divided, the front grade can not be divided!). All control systems can be implemented on the remote control; the wireless control part is embedded in the integrated voltage and current console to display intuition.

7. Wireless control power supply (optional);

8. The instrument uses LCD display. It can monitor the voltage and current of the power supply, the output voltage and current of the regulator, the output voltage and current of the upconverter.

9, with the function of power break protection, during the upflow test, if the power is suddenly lost, the voltage of the voltage regulator is automatically reset to zero position (with zero position indication) after the power switch is repeated again (after the manual switching air switch on the control cabinet panel), and then the operation of the front stage, post stage, upflow and downflow can be carried out, and the belt is strictly avoided. Blow up the power of the superior power;

10, 7 inch 10 inch 15 inch screen or computer host control can be selected according to user needs.

2.1:1 2. action time test: 0.001~99999.999S

1 full automatic control current increase, decrease

2, 64 temperature inspection can be customized according to the requirements of the temperature range of the tested tester.

11, automatic and manual operation.

2. The current, voltage, transformer and the temperature of the tested parts in the test process are displayed in the form of tables and curves, and can be transferred to other computers for further analysis and archiving. The data is based on Excel spreadsheet format to facilitate conversion between charts, curves and data. The text is in word format.

3. Set the test current according to the need. The test current is stable and reliable, and is not affected by the system or external factors.

4. The allowable temperature of the specimen can be set according to the needs. The system automatically adjusts the given maximum current, and displays and records the maximum working current at this time when the set temperature is reached, that is, the maximum working current at the maximum allowable temperature (or the maximum working current under the set temperature).

5. It has the lowest current and temperature and the highest value of the transformer and the specimen. It has the function of exceeding the limit value automatic alarm. It has reliable self protection function of overheat, overcurrent, overvoltage and short circuit.

6. The test number, test current, interval time, upflow rate and maximum current duration at the allowable temperature are set for the same test.  After the test is started, the device is automatically completed by the device. The cycle test can be!

7, before the test, all parameters can be set at once on the touch screen, so as to make the operation simple and clear.

8, when encountering overcurrent, overvoltage, short circuit, over temperature and loss of pressure, it has necessary protection and audible and visual alarm signals. There is no need to produce a destructive alarm factor for the test device, and a sound and light alarm can be sent out. The operator makes the corresponding treatment according to the actual situation after learning the alarm. No time is known after the alarm. The device stops automatically.
